VOISEY’S BAY WIND ENERGY PROJECT
December/2019
Voisey’s Bay Mine Expansion ProjectUnderground mine to extend LOM to 2032
Underground mine development will increase energy requirement due
to ventilation/heating systems.
▪ Previous energy solution: 6 new diesel generating units
▪ Wind Energy Project: can replace diesel generators reducing operational costs and emissions
ENERGY SOLUTION
Existing Site (Open Pit + Concentrator)
Future Operations(Underground Mines + Concentrator)
Power Supply 6 x 4.4 MW diesel generators6 x 4.4 MW diesel generators6 x 6.2 MW diesel generators
Average Energy Demand 11.8 MW 35 to 40 MW
Annual Fuel Consumption 25,180,550 L 80,000,000 L
Annual GHG Emission 67,695 T CO2e 215,000 T CO2e
Voisey’s Bay Wind Project ConceptWind has proven the best solution to offset diesel
WIND MEASUREMENT
▪ Wind energy solution started being investigated in 2012
▪ Met tower installed in 2013. After initial assessment showed potential good results
▪ Assessment needs to consider both power and heat demand for a comprehensive energy solution
Voisey’s Bay Wind Project ConceptDefining the optimum size and turbine manufacturer
▪ As Voisey’s Bay is an off-grid site the challenge is to optimize the size of the Wind Farm
▪ Unlike other projects, the optimum size is not necessarily where the best capacity factor is achieved
▪ Assessment was done considering different turbines, diesel displacement, wind data and load profile
Turbine A
Turbine B
Turbine C
Voisey’s Bay Wind Project ConceptWind Project can displace 10ML of diesel per year
CONCEPTUAL LAYOUT
▪ Potential layout studied at concept design
▪ Optimal solution would have 4 wind turbines, with ~23MW of installed capacity
Project Info
Installed Capacity 22.4 MW
Capacity Factor 30.5 %
Average Wind Generation
6.8 MW/year
Wind Penetration 17,9%
Fuel Savings 10.3 ML/yr
Annual GHG Emission (CO2eq)
27,801 t/yr
Voisey’s Bay Wind Project ConceptA microgrid controller can be used to smooth the transition between diesel and wind production to meet load requirement
